Wish I had this one:

Cone, James H. The Spirituals and the Blues. New York: Orbis Books, 2000. This book reviews some important interpretations of slave songs by authors such as Allen (Slave Songs of the United States) and Richard Wallaschek (Primitive Music [1893]). Cone then goes on to discuss the theological interpretations of the spirituals in relation to the experience of black slaves. Cone states that his purpose is to, "Examine the statement of black experience in the blues as compared with that in the spirituals, investigating their similarities and dissimilarities from both theological and historical view points" (6). His work here is interesting because it examines the spirituals of slaves as an expression of their feelings and goes on to discuss the various meanings of God and Heaven in their songs.
